eval javascipt
To evaluate JavaScript code in Delphi, you can use the TWebBrowser
component. Here's an example of how you can do it:
procedure EvaluateJavaScript(const JavaScriptCode: string);
var
WebBrowser: TWebBrowser;
HTMLDocument: IHTMLDocument2;
HTMLWindow: IHTMLWindow2;
begin
WebBrowser := TWebBrowser.Create(nil);
try
WebBrowser.Navigate('about:blank');
while WebBrowser.ReadyState <> READYSTATE_COMPLETE do
Application.ProcessMessages;
HTMLDocument := WebBrowser.Document as IHTMLDocument2;
HTMLWindow := HTMLDocument.parentWindow;
HTMLWindow.execScript(JavaScriptCode, 'JavaScript');
finally
WebBrowser.Free;
end;
end;
You can call the EvaluateJavaScript
procedure and pass the JavaScript code you want to evaluate as a parameter. The code will be executed in the context of the web browser control.
Please note that the TWebBrowser
component uses the Internet Explorer rendering engine, so make sure you have Internet Explorer installed on your system.
I hope this helps! Let me know if you have any further questions.
